Mayberry

Carlos and I arrived around 11:00 PST. It was a mild and partly cloudy day with a little breeze. The staff gauge read 45 cm.

I downloaded met, camera, and USB GHG data. The camera had lost its time so we reset it; it probably needs a new internal battery. Hopefully that will help with the problem of underexposed photos, too. The camera photos are timestamped starting Jan 1, 1980.

The eosGP data seems to be bad again. We're waiting for replacement sensors from Eosense before we can swap out this probe.

I downloaded the FD data and cleared its memory. Carlos cleaned flux and rad sensors. The wash reservoir was 20% empty; we refilled it. I left a prophylactic mothball in the met datalogger box.

We raised the floating boom up briefly to remove the fluorometer cable. That was brought back to the lab to test the fluorometer.

I collected a last batch of water samples for Isabel around 11:30 PST.

Carlos used his iPad to take some LIDAR shots of the tower.
